I recently read that NHTSA.GOV has webpages of Technical Service Bulletins (TSBs) specific to vehicle year, manufacturer, and model. However, I didn't find them easily and emailed the webmaster for help. The reply states: "To look up Technical Service Bulletins (TSBs) which are known as Manufacturer Communications on our website go to NHTSA | National Highway Traffic Safety Administration click on the Recalls tab. Enter your vehicle's Year Make and Model, then click Search. Under the vehicle information, you will see a section for Manufacturer Communications click the Blue number. There you will find the Manufacturer Communications that have been issued for that year, make, and model." There is no search function for finding TSBs that are relevant to a particular vehicle problem on the NHTSA website. Therefore, I created a file which contains a brief description of the subject of each TSB for 2013 Ford CMAXs and the URL of the TSB. It can be searched for keywords by loading the file into any document software that has a search function. The file is attached for those who would care to use it to help diagnose the cause of CMAX problems. (Many of the TSBs were issued for a broad range of model years. (Although the NHTSA website has separate web pages for CMAX Energi models, many of the TSBs in my CMAX file also cover the CMAX Energi model.) In addition to the TSBs, the NHTSA website also provides webpages of complaints from owners about vehicles of specific year, manufacturer, and model. In the case of the 2013 Ford CMAX, a few failure modes were the subject of a large number of complaints. Among these is unexpected discharge of the 12 volt battery, which I have experienced repeatedly, and which a local Ford dealership has been unable to cure, notwithstand billing me hundreds of dollars for trying. Had I all the information available from NHTSA to show them, I suspect that at least I could have avoided paying the dealership for reprogramming all CMAX's module firmware, and perhaps been able to point them is a direction that would have led to success. (My workaround is to carry a voltmeter and 12V SLA "jumpstart" battery in the vehicle which I can use if stranded in a location where I can't plug in my battery charger.) 2013 FORD CMAX Technical Service Bulletin URLs & Brief Descriptions - NHTSA.GOV.txt
